AI Adaption within SMEs: Analysis of Impedances and Suggested Approaches
No full textIn this paper, we present the main obstacles faced by small and medium-sized enterprises (SMEs) when implementing artificial intelligence (AI), and suggest a novel “plug and play” guided approach for further integration. In order to identify the relevant barriers, we first compile results from recent literature reviews that address challenges specific to SMEs and AI. Then, based on the AI maturity model for SMEs by Schuster et al., we analyze the current status of AI in local German SMEs with which we have worked in the context of the “KI-Labor Südbaden” project. Based on the results of the analysis, we detail a structured approach utilizing pre-identified successful AI implementations as the basis for further technological development. By structuring their AI integration on known successful use cases, SMEs have the chance to leapfrog their AI development and remain competitive in today’s landscape

No full textDie vorliegende Erfindung betrifft Vorrichtungen zum Uberwachen und Optimieren einer zeitlichen Triggerstabilitat einer extrakorporalen Kreislaufunterstutzung sowie Steuer- und Regeleinheiten zur extrakorporalen Kreislaufunterstutzung, umfassend eine solche Vorrichtung und entsprechende Verfahren. Entsprechend wird ein Verfahren zum Uberwachen und Optimieren einer zeitlichen Triggerstabilitat einer extrakorporalen Kreislaufunterstutzung vorgeschlagen, umfassend die Schritte: Empfangen eines EKG-Signals eines unterstiitzten Patienten uber einen vorgegebenen Zeitraum; Bestimmen von P-Wellen, R-WelIen, und T- Wellen aus dem empfangenen EKG-Signal; und Bestimmen eines vorgegebenen Triggersignals aus dem EKG-Signal eines aktuellen Herzzyklus unter Berucksichtigung mindestens einer erfassten P-Welle und/oder mindestens einer erfassten T-Welle.The present invention relates to devices for monitoring and optimizing a temporal trigger stability of an extracorporeal circulation support means and also open-loop and closed-loop control units for extracorporeal circulation support means comprising such a device and corresponding methods. Accordingly, a method is proposed for monitoring and optimizing a temporal trigger stability of an extracorporeal circulation support means, comprising the following steps: receiving an ECG signal from a supported patient over a given time period; determining P-waves, R-waves and T-waves from the received ECG signal; and determining a given trigger signal from the ECG signal of a current cardiac cycle, taking account of at least one detected P-wave and/or at least one detected T-wave.La présente invention concerne des dispositifs de surveillance et d'optimisation d'une stabilité de déclenchement temporel d'un moyen d'assistance circulatoire extracorporel, ainsi que des unités de commande en boucle ouverte et en boucle fermée pour le moyen d'assistance circulatoire extracorporel comprenant un tel dispositif, et des procédés correspondants. En conséquence, un procédé est proposé pour surveiller et optimiser une stabilité de déclenchement temporel d'un moyen d'assistance de circulation extracorporelle, comprenant les étapes suivantes : la réception d'un signal d'ECG provenant d'un patient pris en charge sur une période de temps donnée ; la détermination d'ondes P, d'ondes R et d'ondes T à partir du signal d'ECG reçu ; et la détermination d'un signal de déclenchement donné à partir du signal d'ECG d'un cycle cardiaque actuel, en tenant compte d'au moins une onde P détectée et/ou d'au moins une onde T détectée

A Study on Speech Emotion Recognition in the Context of Voice User Experience
No full textWith the increasing popularity of voice user interfaces (VUIs), there is a growing interest in the evaluation of not only their usability, but also the quality of the user experience (UX). Previous research has shown that UX evaluation in human-machine interaction is significantly influenced by emotions. As a consequence, the measurement of emotions through the user’s speech signal may enable a better measure of the voice user experience and thus allow for the optimization of human-computer interaction through VUIs.
With our study, we want to contribute to the research on speech emotion recognition in the context of voice user experience. We recorded 45 German participants while they were interacting with a voice assistant in a Wizard-of-Oz scenario. The interactions contained some typical user annoyances that might occur in voice-based human-computer interaction. Three analysis modules provided insight into the voice user experience of our participants: (1) a UX-questionnaire; (2) the UEQ+ scales for voice assistants; (3) speech emotion recognition with OpenVokaturi

3-D-Printed Torque Sensors: A Review
No full textTorque sensors find utility across diverse domains, such as drive and conveyor technology, robotics, and research and development. Multiple sensing principles are applicable for torque measurement. Notably, the resistive effect, utilizing strain gauges, is a prevalent method. In recent years, 3-D printing technology has experienced significant growth, facilitating the production of physical objects and functional structures through many 3-D printing processes and materials. As a result, 3-D printing has attracted attention in the field of printed electronics and sensors, leading to various sensor developments in research projects using 3-D printing techniques. This review offers an overview of the current state of research concerning 3-D-printed torque sensors. In terms of transparency, this review adheres to the preferred reporting items for systematic reviews and meta-analysis (PRISMA) method, a systematic literature review approach. The identified sensors undergo analysis based on sensing principles, 3-D printing processes, printing materials, and the extent of 3-D printing application. Furthermore, prospective research directions are delineated
Ameise
No full textDie Infragestellung des Menschen findet für uns gerade durch die kleinen Tiere statt. Ameisen, Wespen, Parasiten. Wie generieren sie ihre Umweltbezüge? Wie kommunizieren sie miteinander? Wie sind »soziale Tierarten« sozial? Wie konturiert sich unsere Empathie in Tiere, die nicht Säugetiere oder Haustiere sind? Und wie geschehen Begegnungen mit ihnen, Sorge für sie? Welche Übertragungen nehmen wir auf sie vor – etwa wenn wir anthropomorph von Ameisenköniginnen und Arbeiterinnen sprechen? In wie weit nützt objektivierende Forschung doch auch immer Übertragungen, ein »Von sich auf Andere schließen«? In wie weit nutzen wir dabei Mit-Gefühl? Und in wie weit zerstören manche Arten von Forschungen gerade dieses

No full textDoes advanced footwear technology improve track and road racing performance? An explorative analysis based on the 100 best yearly performances in the world between 2010 and 2022
Get PDFAdvanced footwear technology (AFT) is currently being debated in sports. There is a direct evidence that distance running in AFT improves running economy. In addition, there is indirect evidence from competition performance for improved running performance from using AFTs in middle- and long-distance running and sprinting events. However, the extent to which world-class performance is affected across the full range of track and road racing events between genders has not been systematically analyzed. This study examined publicly available performance datasets of annual best track and road performances for evidence of potential systematic performance effects following the introduction of AFT. The analysis was based on the 100 best performances per year for men and women in outdoor events from 2010 to 2022, provided by the world governing body of athletics (World Athletics). We found evidence of progressing improvements in track and road running performances after the introduction of AFT for road races in 2016 and AFT for track racing in 2019. This evidence is more pronounced for distances longer than 1500 m in women and longer than 5000 m in men. Women seem to benefit more from AFT in distance running events than men. For the sprint events (100 m to 400 m hurdles), the peak performance gains in 2021 and 2022 compared to the pre-AFT period ranged from 0.6 to 1.1% and from 0.4 to 0.7% for women and men, respectively. For middle-distance events (400 m to 3000 m steeplechase), peak performance gains ranged from 0.6 to 1.9% and from 0.6 to 0.7% for women and men, respectively. For distances from 5000 m to the marathon, performance gains ranged from 2.2% to 3.5% and 0.7% to 1.4% for women and men, respectively. While the observational study design limits causal inference, this study provides a database on potential systematic performance effects after introducing advanced shoes/spikes in track and road running events in world-class athletes. Further research is needed to examine the underlying mechanisms and, in particular, potential gender differences in the performance effects of AFT
